Hi, Does anyone know of a method for writing text to the graphics window, where there is *no* plot? Basically, I have developed a 'significance test' and I would like the output on the graphics window to say something about the input parameters and the stats of the significance test. Any help would be appreciated. Cheers, Sam.

Hi, Does anyone know a method for adding a linear/polynominal trend to a simulated arima model using the arima.sim function? Any help will be greatly appreciated. Cheers, Sam.

Hi, Is there a function in R that lets one represent an integer in binary format for a given number of bits? So an example would be.... > binary.function(num=5, num.of.bits=8) > "00000101" Or, is this something I have to write myself? Any help would be appreciated. Cheers, Sam.

Hi, I am considering whether or not to buy an apple mac. I have noticed on one of the R FAQs for Mac OS X that you cannot install packages from other OS's if C++ code is contained. My question is: Is it possible to build the package sources containing C++ code on the Mac and then install them? Thanks in advance, Sam.

Hi, I am trying to run a very computationally expensive procedure in R-2.0.0. and the process always gets killed after approx 8 minutes. This procedure calls some of my own C++ code - in case it was this code causing a memory leak I unload and then reload the .so file every time, however I still get the same problem. The procedure is run 16000 times and always calls the lm() function. My

Hi, I have written a Gamma Test package. The Gamma Test (GT) is a non-parametric non-linear modelling tool that estimates the variance of the noise in an input/output dataset (including time series). The GT was recently given a rigourous mathematical proof in the Royal Society. All the papers on this work to date can be found at Antonia Jone's (Professor of Neural and Evolutionary

Hi, I am trying to install the OOP package (v0.4-2) from Omega Hat using the R CMD INSTALL (I have also tried untarring the package an using R INSTALL) but no joy. Here is the following error... $] R CMD INSTALL OOP_* * Installing *source* package 'OOP' ... ** libs gcc -I/usr/local/lib/R/include -I/usr/local/include -D__NO_MATH_INLINES -mieee-fp -fPIC -g -O2 -c RtreeApply.c -o

Hi, I want to set up a dynamic link between a library e.g. myLibrary.a and a C++ file myProgram.cc to use in R. Is this possible? If so how does one go about doing it? Any help will be greatly appreciated. Cheers, Sam.

Hi, Does anyone know of a function (or a method) of generating simulated time series with non-uniform embeddings? Any help will be greatly appreciated. Cheers, Sam.

Hi, Linking C++ dynamic libraries has become the bane of my R life. I have a piece of C++ code that I would like to make into a .dll (to call into R). However, this piece of C++ code needs to be linked with a .dll or .lib - which I have been created in Visual C++. Is it possible to link this for use in R? If so, how do I go about doing this is MINGW? I am running R1.9.0 on WinXP. Any

Hi, Does anyone have any ideas on how to show greek letters on the x and y axes? I have tried > plot(x,y, xlab=expression(delta), ylab=expression(gamma)) but the output on the x-axis is "d" and on the y-axis it is "g". Any help will be very much appreciated. Cheers, Sam.

Hi, I am trying to write an article for the Rnewsletter, but keep getting errors. I have googled around for some decent examples that contain figures, maths, etc but with no joy. Would any be so kind as to send me an example article in latex code? Cheers, Sam.

Hi, I am trying to make a neural network learning a "noisy sine wave". Suppose I generate my data like so.. x <- seq(-2*pi, 2*pi, length=500) y <- sin(x) + rnorm(500, sd=sqrt(0.075)) I then train the neural net on the first 400 points using c <- nnet(as.matrix(x[1:400]),as.matrix(y[1:400]), size=3, maxit=10000, abstol=0.075, decay=0.007) Inspecting the fit of the training

Hi, Can anyone tell me how to construct a simple VAR(1) time series with two variables using the dse package? I would like to end up with two time series y_1t = \phi_11 y_1,t-1 + \phi_12 y_2,t-1 + e_1t y_2t = \phi_21 y_1,t-1 + \phi_22 y_2,t-1 + e_2t Best regards, Sam.

Hi, I am trying to make my own package in Windows XP with R 1.9.1. using Rcmd build/ Rcmd. The initial Rcmd build compiles ok with no error messages. However, when I run Rcmd check it runs ok up until * checking for file 'GammaTest/DESCRIPTION' ... OK * checking if this is a source package ... OK * checking whether package 'GammaTest' can be installed ... ERROR Installation
